Hanging the boiler

NOTICE: Before hanging the boiler.
▶ If pipes require reducing in length this is best done
before they are fitted to the boiler.
NOTICE: Lifting the boiler.
▶ Lift the boiler using the handling holes at either side
of the frame.
Do not lift the boiler by the air gas manifold or control
box.
System pipes may be run vertically up behind the boiler or below it.
The boiler mounting points on the wall frame are indicated in figure 28.
Ensure the wall frame sides are not slightly splayed out after mounting;
move the sides in to allow the boiler to slide on to frame.
Fig. 28 Wall frame boiler mounting points
▶ Lift the boiler onto the wall plate.
▶ Ensure that the boiler is presented slightly higher than the wall frame
so that the slots in the boiler frame slide over the mounting points on
the wall frame.
▶ Lower the boiler onto the wall frame mounting point, ensure that the
wall frame mounting points are fully engaged with the slots in the
boiler frame.

▶ * Do not use solvents, adhesive or lubricant when
pushing the pipe onto the rubber connector.
Figure 32 gives the pipe work dimensions with respect to the mounting
surface.
▶ Fit the condensate discharge pipe as far back as possible to the wall
to ensure easy fitting of the boiler bottom panel.
▶ Route the condensate pipe to an appropriate discharge point, refer
to section 4.4.
▶ Plumb up to the wall frame with 22mm pipe.
▶ Ensure that there is enough pipe to insert 25mm into the rubber hose
